37 Electrical System problem of the 2018 Audi Q5

Failure Date: 10/24/2024

2018 Audi Q5 (2. 0, 40k miles, excellent condition) experienced severe electronic failure, due to sunroof drainage lines depositing water into the rear side wells where sensitive electronics are housed, impacting all tail-lights, wipers, sensors, internal dashboard sensors, etc. , rendering the car highly unsafe and undrivable. The issue is a design and manufacturer defect that has allowed rainwater to leak into the rear side compartments destroying sensitive electronics & wiring, from faulty/kinked drain lines in the sunroof (according to the Audi technician from my local Audi store), rendering the vehicle undrivable. It was obvious, repeatable, and avoidable. Worse this issue was misdiagnosed by the same Audi store, causing extra parts & labor expenses that didn't solve anything. It took my Audi store over a month to diagnose the issue correctly. There were also significant investigative/diagnostic charges from my Audi dealership. There were also significant repair expenses to replace all water-logged equipment, including the electronics control unit (ecu). This should be a clear recall item.

38 Electrical System problem of the 2022 Audi Q5

Failure Date: 10/06/2024

My car cut off while I was driving [xxx]. My family including my [xxx] was in the car when the car shut off mid drive. No warning nothing. Power was on but the steering wheel locked and the brake pedal was firm. I could not switch gears nothing. It's a Sunday so I had the car towed to my home. 10/7 I have the car towed to bell Audi in edison NJ and was told it's my alternator. I work from home, I barely drive 10 miles a week. I use my car to pick my daughter up from school which is close to home. I have researched and found this is a common issue with Audi cars that are not old. At 13k miles I should not have this issue. We could've died on the highway as that is where I was heading towards. I checked my VIN and found this is a common issue which is not acceptable as we almost died in the car as it stopped short and scared all of us and locked up.

39 Electrical System problem of the 2018 Audi Q5

Failure Date: 08/19/2024

The comfort control module in the trunk of the car was sitting in water due to an ingress of water coming in the car. The car would not start due to this water ingress and could have shut off completely on the freeway or while driving. This caused my car to completely shut off and malfunction. There were no warning lamps or messages of the problem. I found out about the problem by taking the car to the Audi dealership. They originally thought the problem was the gateway module which has already been recalled due to the same problem of an ingress of water. The Audi dealership has claimed that the ingress of water is from a clogged drain pipe in the sunroof. They said there is nothing you can do to prevent this from happening.

44 Electrical System problem of the 2018 Audi Q5

Failure Date: 07/10/2024

Car was left outside for two weeks while we were gone on a trip. When we returned and attempted to start the car numerous warning lights went off related to turn signals, tail lights, engine ignition, key recognition, etc. We were able to drive the car home but the turn signals and tail lights were malfunctioning and the engine would lose power unexpectedly. Upon researching on Audiworld forums I came to learn I should check to see if there was any moisture in certain areas, including the rear fuse box area at the rear of the car. I checked that location and found many inches of water in the fusebox!!! I learned that many, many people with Q5s have had the same problem which is rainwater entering the vehicles electrical system due to non-operable sunroof drain ports. Yes, I searched and found an unrelated recall 90s9 but the dealer said this was not the issue, the issue is non-operable sunroof drains and the repair cost is $8,000. Having no idea of the danger I was placing my family in by driving this vehicle while its electrical system was swamped with water, I feel a class action lawsuit should be brought against the company for damages for material, labor, as well as the risk of injury or death I placed my wife and I in by driving this vehicle under such unsafe conditions. I noted there was a suit settled for this issue with other models, but not the 2018 Q5. [xxx] v Audi/volkswagon [xxx] . The idea that someone should have to face death for leaving their car in the rain does not even pass the laugh test. Someone in Audi's risk management department needs to address this and make owners whole again. Please advise. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

45 Electrical System problem of the 2016 Audi Q5

Failure Date: 07/06/2024

On [xxx] at around 2:22 pm, as I was driving, the car shook, pulled up to red light and the car would not move. It shook, rattled and died. The epc light came on. I owed the car back to the dealership. I noticed that parts of the car next to the muffler and the tailpipe were belong held together with making tape. I received a call from the dealership from tony. He said the car was fixed by the owner. No clear verification that the dealership owner is as trained or licensed mechanic. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

47 Electrical System problem of the 2024 Audi Q5

Failure Date: 06/12/2024

The dash board lights all came on, windows rolled down, car could not be controlled and couldn’t put the gear in park. After further research on the internet, I found that there was a recall on 288,000 q 5s in 2021 because of this issue. Dealer said the “gateway system” that controls all the communication died and they had to replace it. I think the 2021 issue is not completely resolved.

48 Electrical System problem of the 2018 Audi Q5

Failure Date: 05/03/2024

On may 3, 2024, while driving to work, the vehicle acutely started to make a loud clicking noise in the engine compartment. I parked the vehicle and looked for a warning light indicator on the dashboard to determine the problem, but no indicator light emerged. I then called Audi omaha and spoke with the service manager who kindly arranged to have my vehicle picked up and a loaner dropped off. I did ask at that time whether it was safe to have somebody drive my vehicle to Audi given the severity of the noise and I was told that since there was not a warning light on the dashboard, it would be ok. I later discovered that my vehicle stalled on the way to Audi omaha and required a tow. On may 6, 2024, I received a report of the problem and the estimate for repairs. It was explained that the head of a spark plug had broken off into the engine causing the piston to make contact with the valve in cylinder 3 resulting in engine damage which was beyond repair. Additionally, a second spark plug had been misfiring for several days. The estimate to replace the engine: $9,282. 03. To my surprise, the multi-point vehicle inspection report I received on the same day reported that everything (aside from rear brake pad wear) passed inspection – including the engine and spark plugs! on may 7, 2024, I called Audi omaha to express my concern that an entire engine would need replaced on a 6-year old luxury vehicle with only 60,000 miles and spark plugs that were replaced at 40,000 miles prior to my purchase of the vehicle. Even more concerning is that no warning light indictor ever displayed on the dashboard (despite being informed that the vehicles computer system had detected changes in the engine compartment 2-days prior to this event). Because of these glaring safety concerns, this issue was escalated to the Audi central region division who declined to provide assistance despite the faulty spark plug and the malfunction of the warning indicator light.

50 Electrical System problem of the 2018 Audi Q5

Failure Date: 04/02/2024

I got a safety system malfunction! fault. I took it to aan Audi dealer and they said it was an issue with a harness under the passenger seat. Tech notes here references a service bulletin. Air bag occupant sensor - replace | faults present b1225f1 - TSB 2051242/7 -- per TSB apply wiring ties to secure and prevent faults from returning -- not covered under extended warranty policy. Not sure why this isn’t covered under extended warranty or a recall. It basically disables the passenger airbag. I have seen other Audi vehicles with recalls for similar issues with harness under the passenger seat. I think they have a design issue but are wanting to charge me (and probably others) $220 to diagnose and $695 plus tax to put two wire ties on the harness to supposedly fix (or bandaid) a bad harness.

51 Electrical System problem of the 2018 Audi Q5

Failure Date: 03/23/2024

-car shut down (engine off, battery still functioning) while driving. Car went into neutral. -lost power steering and other functions after about 20 seconds of the engine shutting down. -immediate life-threatening danger while driving to us and surrounding drivers and pedestrians -no inspection or police report yet. -the car has not been driven since the incident and so the problem has not been reproduced yet. Upon inspection of the trunk area (2018 Audi Q5), we found about 4 inches of water. This has been attributed to clogged sunroof drains causing water to flow into the trunk and short out electrical components.

52 Electrical System problem of the 2021 Audi Q5

Failure Date: 02/21/2024

Warning lights came on and car completely stopped. Towed to dealer where we were told that gateway control module part no 80c907468f has failed due to water damage. Dealer informed us that this is not covered by warranty for this reason. We do not believe we spilt any water there as it is located under the back passenger seat. We asked dealer to proceed with repair when we were informed that the part is on back order. We assumed this would be a matter of days or perhaps few weeks. It has been 3 and half month and no eta yet. I found on Audi world user group that this is a common problem with this model and others have suffered similarly. I believe the oem is responsible for making parts available within a reasonable time. In dealing with Audi America and the dealer they offered no remedy for this problem. And I am with out a car now going into 4 months. Surely they must be responsible to consumers for providing the services to maintaining the purchased vehicle operating!.

Please advise.

57 Electrical System problem of the 2014 Audi Q5

Failure Date: 12/01/2023

On 12/1, around 7:20am my fiancé and I were getting ready to leave for work; there was frost on the car so my fiancé went out to start it and turn on the defrosters. After starting the car, he turned on the heater and front and rear defrosters, he then went inside to retrieve some items we needed to load into the car. He was inside for about 5 minutes before coming out to see smoke emanating from right side of the trunk, which quickly turned into a small fire, whose point of origin was the rear fuse compartment. He ran inside to grab water to try and put it out, but due to how quickly it was spreading, as well as the fact that it was electrical nature, the water only served to temporary diminish but not extinguish the flames. We then used an abc rated fire extinguisher from our kitchen, which did suppress and extinguish the fire. The vehicle still started, and we were able to drive it from our driveway to the side of our home, however, with the risk of it igniting again or creating any other failures, in addition to the guidance provided by our insurance company and Audi corporate, we had the vehicle towed to an Audi dealership for further investigation. There was no indication prior to this that would lead us to believe the car would catch fire. We consider ourselves to be lucky that we were not driving as we would have no way to extinguish the fire on the side of the road. Since this incident, an investigation was done by Audi corporate. It was determined that there was corrosion within the right trunk compartment caused by water at some point which caused a short considering the body module and fuses are located there. However, Audi claims no responsibility in the water getting into the trunk or any manufacturing defects. Upon our own research though, we’ve seen many reports of q models have sunroofs draining into the interior. The car has since been totaled by insurance due to repair estimates nearing $29,000 and taken to copart auction.

58 Electrical System problem of the 2020 Audi Q5

Failure Date: 11/26/2023

We were driving today at around 11:30am and all of a sudden the “Audi presense” light came on at the same time the car brakes abruptly slowed down the car for about 5 seconds or so and then released. Today is a beautiful sunny day and there were no vehicles anywhere or anything in roadway on the road we were traveling on. The jerking /abrupt slowdown really surprised us. We will go to Audi dealer ASAP but now we don’t trust when it will happen again. A car could have hit us from behind.

59 Electrical System problem of the 2023 Audi Q5

Failure Date: 11/15/2023

The digital dash screen system continually disconnects from the phone and will not reconnect. It disconnects during 911 calls. It disconnects when navigation is activated. It is very dangerous to drive a car that does this. I’m sure I paid thousands a dollar for this digital dash screen system, and is very frustrating that it does not work yet the Audi dealership and Audi corporate refused to, and or cannot fix my car. I’ve done research and it appears this is a very common problem and the service department at the dealership says they hear this complaint all the time.

62 Electrical System problem of the 2018 Audi Q5

Failure Date: 10/13/2023

The car was sitting in the driveway in the rain. I went out to get something out of it and the car was dead, but the back wiper was going, the rear lights were on and the driver side windows went down. I had it towed to the dealer and they told me water had gotten into the area in the back left wheel well where the comfort module is located. The dealer tried to say there was something wrong with the rear hatch but there isn’t. I’ve read account after account online of this exact issue happening to other owners and it caused by a defective sunroof drain. It drains right into the rear hatch with the module. They quoted $9000 for the repairs.

64 Electrical System problem of the 2018 Audi Q5

Failure Date: 09/25/2023

Comfort control module (j393) is malfunctioning due to water getting into the wiring components and surrounding areas. The rear lighting stops working all together; no taillights, no brake lights, no turn signals, no license plate lights, and no lights when backing up. The problem has been reproduced by an authorized dealer. The component was removed by the dealer and noted of water inside the module and corrosion on the pins/ internals because of the water. The warning lamps occurred at the same time the lights stopped working. There was never any "prior to" warning. The warnings disappear randomly, no set time until they cleared. I am assuming once the module dries out over time is when the warnings start to clear but that is just speculation. Unknown cause of the incident, but water is getting into the inside of the car somehow.

65 Electrical System problem of the 2018 Audi Q5

Failure Date: 09/21/2023

Control modules located next to the gateway module that was recently recalled are getting wet and shorting out. Tail lights, brake lights, turning signals, license plate lights, and reverse lights all stop working. Once the area is dry, the lighting works only sometimes. I am not ever sure if the lights work or not while I'm driving and am concerned about getting rear-ended because of the lights being out and me not knowing.

70 Electrical System problem of the 2018 Audi Q5

Failure Date: 08/18/2023

Rear sunroof drain leak into major electronic components. 2018 Q5 with 61k miles after heavy rain started receiving all kind all errors including lights and ignition. Upon inspection Audi service has stated that hvac control module has shorten (the area with the module in the left rear portion of the trunk filled with water), quoting repair of the module and insisting to replace sunroof drain hoses for total of $5k. Insurance has agreed to cover module replacement due to the flood of approx. $2,5k, however drain hoses and deducible with another $2,5k would not be covered and is on me. Mechanic in the Audi service several times noted that that this is common issue with Q5 and q7s. , I am so frustrated and do not understand how come the Audi car the owner shall be responsible for any cost of such if it is unclear: 1. How and why the water gets there through the closed sunroof in such amount to flood electrical equipment. Are all Audi sunroof seals so bad that they fail in 6 years? 2. I had serviced the car in the Audi for up to 60k, and no one ever cleaned the drains there or advised me of such (all is needed a small note for me)? why did I pay extra to service car in the official dealerships? 3. How Audi could sell a vehicle with such design flaw, placing weak drainage hose through the electrical equipment compartment, considering they just had a class action lawsuit over sunroof leaking but on different models and model years.
